…login_with :factory_name
This means we no longer need to add a new macro every time we add a new type of user.
You just supply the reference to the factory name and the currently logged in
user is available as logged_in_user.
Happy days!

…file.
Instead of using @import to pull in the other stylesheets it acts like a proper manifest by requiring these files.
This fixes errors like 'ActionView::Template::Error (File to import not found or unreadable: site_bar.' when running in production mode.
